It has been announced over at Capcom Unity that Peter 'Combofiend' Rosas will be leaving Capcom after five years of working for the company.
Peter cites his interest in getting people to play Capcom's fighters during his time there.

As indicated in the farewell message, Peter feels as though it's time for a new generation to work on the company's games.

"I’ve been fortunate enough to work on the games that shaped my life, a definite dream come true, but now I feel it’s time for the next generation to be able to do the same," said Peter. "There’s no doubt in my mind that the current generation has their own unique ideas that will push Capcom’s fighting games forward in terms of innovation and evolution."

He mentions being interested in seeing what ideas come up in the future from the newer generation. He believes that they will provide innovative and unique ideas.

Peter notes that the "interactions and experiences" that's he had with people are among his most memorable experiences. Things appear to be in good terms as he notes that he is will be joining the community again as a Capcom fan.

It remains to be seen if he will return to competing now that he is no longer employed by Capcom. He was, after all, a top level competitor in Marvel vs. Capcom 3 and Street Fighter 4 back in the day.

Though Peter was a very strong Marvel vs. Capcom 2 and Capcom vs. SNK 2 player in his early days, newer players in the community took particular notice of him after his legendary "Bionic Arm" moment against Marn at Final Round 14.

In Marvel vs. Capcom 3, he was particularly known for his innovation of Nathan Rad Spencer's meta. Especially the usage of the invincible "Bionic Arm" hyper combo.

Despite being in situations where he'd have two of his characters KOed, he'd be able to make some rather spectacular comebacks with just Spencer.

In Street Fighter 4, he was well regarded as a talented Abel and, later on, Oni player. His play style emphasized his very strong rushdown abilities.

For awhile, he also was a member of CompLexity / Cross Counter along with Gootecks and Mike Ross. Shortly after leaving, he was employed by Capcom.

During his time with Capcom, he was a community manager. He also assisted with the gameplay and balance of Marvel vs. Capcom: Infinite, Street Fighter 5, and Ultra Street Fighter 4.

He's been credited as an associate producer for Street Fighter 5 and Marvel vs. Capcom: Infinite, production for Ultra Street Fighter II: The Final Challengers, design in Ultra Street Fighter 4, and public relations for Strider (2014) and Dungeons & Dragons: Chronicles of Mystara.
